 He scored the Finale for full orchestra, again as per Tchaikovsky's practice.The single-movement Third Piano Concerto and the "Andante and Finale" are sometimes played together to form a synthetic "complete" three-movement concerto, but this is without any authority from the composer.Whether Tchaikovsky would have fulfilled his original conception of a standard three-movement concerto, and if so, whether he would have used the "Andante and Finale" music or written new music, is purely conjecture.
